17
Q

Why are cemented prosthesis more Riley to be affected by biological complciaotns

A

Can be difficult to clear cement for the edges leading to biological interactions and complications

18
Q

Give examples of biological complications affect peri implant tissues

A
  1. Peri implant mucositis
  2. Peri implantitis
  3. Plaque induced conditions
19
Q

What is Peri implant mucositis

A

Reversible inflammatory reaction in the soft tissues

20
Q

How many patients are affected by Peri implant mucositis

A

63.4%

21
Q

What is Peri implantitis

A

Inflammatory reaction in the tissues surrounding an implant with loss of supporting bone

22
Q

How many patients are affected by Peri implantitis

A

18.8%

23
Q

How do you assess an implant

A
  1. visually
  2. Palpate it
  3. Is it mobile
  4. Smoker
  5. Oral hygiene
24
Q

What do you examine visually when assessing a dental implant

A
  1. Colour
  2. Consistency; is there any swelling present
  3. Sinus
  4. Recession
25
Q

What type of probe do we use to assess an implant

A

plastic probe

26
Q

How much force should we use to assess an implant

A

25g around teeth

15g around implant

27
Q

What are we looking for when probing around an implant

A
  1. 6 points
  2. Bleeding on probing
  3. Probing pocket depths
  4. Suppuration
28
Q

Do we do BPEs around an implant

A

NO

29
Q

What don’t we use BPEs around implants

A

Because the bone level is more variable around an implant

30
Q

What does implant mobility indicate

A

Implant failure due to loss of osseointegration

31
Q

How do assess the bone levels around an implant

A

Radiographic examination

32
Q

Which radiographs can we take to assess bone levels

A

Panoramic

Periapical

33
Q

When should we take radiographs to assess bone levels of an implant

A

2 yearly intervals
or
if any changes assessed

34
Q

What habit can lead to increased failure risk of implant

A

Smoking

35
Q

By how much can smoking increase implant failure

A

2.6 times

36
Q

Smoking increases the risk of which bioligcla complication

A

Peri implantitis by 36.5%

37
Q

How can periodontal history affect implant success

A

Rate of implant failure/ complications is higher in patient with a history of treated periodontal disease

38
Q

What do we assess when looking at a patients dental history

A

Periodontal health

patietn attendance

39
Q

When looking at etc implant restoration what do we look at

A
  1. Linked units
  2. Contour
  3. cement tupe
  4. Margin postion
40
Q

How do we treat peri implant disease

A

Early and aggressively by:

  1. Giving OHI
  2. Non surgical debridement on a 6 or 3 month basis
  3. Modify the prosthesis ?
41
Q

What can we use to carry out non surgical treatments of implants

A

Plastic carbon fibre enforced scalers are better as they are less likely to scratch the titanium
